My invention relates I mechanism fo transferring bottles or other.-{glass 1 from a. forming machine to an anneal ng oven que r.- An objectof the invention-1s" I 5 to provide practical mechanism for receivingthe hot ware which is conditionas it'i's discharged from the form: ingmachine, and transferring it to the leer without distorting, breaking,marring or.

from the through a spout, device to break I charged dropped a clapperblowing machlne, 1S beneath which is the fall and from which the bottlesare delivered neck end downward into cup-like holders on an endlessconveyor. The bottles are thereby supported in upright position on theconveyor and carried by the conveyor to a point adendless belt conveyorwhich carries them in-' to ithe leer. V

' The holding cups onthe conveyor are specially adapted for holding agreat variety of ware. It is found in practice that .when

, held in this manner there is practically no collapsing of the sides ofthe bottles as they tend to do when they rest for any length of timeontheir sides, as is necessary when the usual means are employed forcarrying the bottles to the leer. Holding the bottles ver tically-in themanner above noted also permits the application of air to cool-thebotbottles which ordinarily cool muchmore slowly than the neck and bodyfportions, without danger of the air being" applied where it will causethe 1 glassto;

check. r

. The present invention provides means for handlingthe glass articleseither singly or in pairs 'or groups where a plurality are delivercdfromthe blowing machine at once. The articles are carried rapidly to theleer entrance, at which point they are laced on a belt which is heatedto avoid (:0 (i checking, and. quickly carried thereby into the leer.The articles throughout their transfer are held out of contact with eachother and handled in such ag mannerthat checking, chipping andother-injuries'are reduced to aminimum. Other objects of the inventionwill appear hereinafter.

The conveyor is driven by or in synchronism with the which the bottlesare delivered. The bottle cally at 26 (Fig. 5) drives a pinion 27. Themotion is transmitted through a shaft 2 8.

(Fig. 1), gears 29 and 30, shaft 31 and ears 32 and 33, the lattersecured to the rive shaft 15.

In order to adjust the cup conveypgso indicated diagrammatibottleblowing machine from that the cups 22 will be in shaft 15 and meshingwith a Worm 35 journalled in lugs on one of the sprocket Wheels 13. Thehub of the sprocket wheels is loose on the drive shaft them'the conveyormay be adjusted.

The cup conveyor for'the greater portion of its length is enclosed in acasing 36 mounted on supports 37. The upper lead of the conveyor issupported on angle bars 38 (Fig. 2) extending lengthwise of the conveyorand carried by brackets-39 attached to the side walls of thecasing. In\order to prevent undue cooling of the bottles in their passage to theleer, there is provided heating means formaintaining a high temperaturewithin shown comprises a burner 40 consisting of a pipe extendinglengthwise within the casing and provided with a multiplicity ofperforas. tions from whichthe burning gas issues, said gas beingsupplied through a pipe 41. The

' point, there is' provided on an arm 47' mounted-to bottoms of thebottles.

which the bottles into and through c upper ends 51 of which are alsopreferably casing is equipped with a smoke pipe 361 and damper 362.

As the bottoms of the bottles usually cool more slowly than the otherportions, owing to the greater thickness of the glass at this J coolingmeans for applying. a blast of air directly against the Such meanscomprisesblowers 42 carried by adjustable pipe sections 43 telescopingwith stationary pipes 44 through which cooling air under pressure issupplied. The blowers 42- are adjustable Vertically to adapt them tobottles of different lengths and are held .in adjusted position by .set,screws 45.

The mechanism fromthe blowing machine to the cup conveyorwill now-be,described. This mechanism, shown particularly in Figures 6, 8, 9

and 10, comprises funnel guides 46 into are dropped neck end first fromthe blow molds, the spouts 50, clappers 52 and their actuatingmechanism.
